IGN looks back to Deus Ex: Invisible War:

Deus Ex has had a huge influence on modern game design. In this rare look back Warren Spector and company look back at The Invisible War and then to the future of the series.

Deus Ex: Invisble War, the second Deus Ex game, can now be purchased from GOG.
The price is $ 9.99 - but then you get wallpapers, avatars, commentary from the developers, soundtrack, manaul and a bit more.

Eurogamer takes look at this game now when the third game Deus Ex:HR has been released. A few highlights:

For a start it's a better shooter than Deus Ex. For a series that prides itself on player agency the tricky gun play of the first game nudged people towards creeping around rather than allowing them to choose between being a sneak or acting like RoboCop.

Then there's the universal ammo concept. No more messing around rearranging ammo in your inventory like an obsessive compulsive - just one clip to rule them all.

That said, for every decent addition Invisible War screwed up somewhere else. It reduced hacking to waiting for a bar to fill up. Even worse, it then rubbed that in by robbing us of the joy of playing a nosy parker who gets their kicks from reading emails that provide tiny insights into life as a bored office worker from the future. The scale of the areas in the game is another bugbear, each seemingly squashed down to the size of a bedsit to help Invisible War to fit on the Xbox.

That said Invisible War's overall attempt at creating a truly malleable story didn't really work. It's too easy to shift allegiance at any point, which undermines the meaning of your choices, and you can miss important parts of the story by sticking to one faction too much.

Invisible War is destined to spend its future living in the shadow of the game that came before it and, now, the game that came after it. But there's enough Deus Ex pixie dust within Invisible War for it to deserve a better fate than being remembered for what it is not rather than for what it is.

Lewis Denby writes an opinion piece at Gamasutra, examining Deus Ex: Invisible War and concluding the game lacks atmosphere:

Consider your favourite example of an atmospheric game. Mine, at present, would be something like BioShock, but I could just as easily pick Half-Life and its sequel, both System Shocks, Silent Hill, Vampire: Bloodlines or a whole host of others. Heck, even something as seemingly innocuous as World of Goo has heaps of the stuff. And the one thing these atmospheric games have in common, always, is a convincingly crafted, tangible, flowing world.

Invisible War lacks this. It's not got anything to do with the size of the hubs, or the minute amount of people populating them -- not as such, anyway. There's just so little pretense of it being part of an actual place. There's a loading screen over every level transition, for a start, so it's never a seamless world. That certainly doesn't help, but it's not a deal-breaker -- a number of the examples above find themselves in a similar position.

More importantly, Invisible War is rendered as a series of disconnected, disorganised game arenas. The layout and functionality of these places simply doesn't work, or make any logical sense. They're boxy, artificial locales that in no way could you imagine people actually working in, relaxing in, living in -- even existing in.
